2 Claims.

This invention relates to heating systems and controls therefor, and has for one of its objects the provision of an economical heating system and control to prevent the dissipation of heat and at the same time to provide sufficient heat to prevent freezing of the water in the radiators and pipes when the system is shut down for the night.

Another object of the invention is to provide such a heating system which is especially adaptable for use in garages and the like, and which is controlled by means operable by one or more doors.

A further ob-ject of the invention is to so arrange the control system that when the garage `l5 door is opened the heating system will automatically stop functioning.

A still further object of the invention is to provide additional control means operable by a lock, which when in locked position will automatically shut oi the heat and also shut off the drafts for the fire in the boiler.

Other objects and advantages will appear as the nature of the improvements is better understood, the invention consisting substantially in the novel arrangement and co-relation of parts herein fully described and illustrated in the accompanying drawings, wherein similar reference characters are used to describe corresponding parts throughout the several views, and then finally pointed out and specically defined and indicated in the appended claims.

The disclosure made the basis of exemplifying the present inventive concept suggests a practical embodiment thereof, but the invention is not to be restricted to the exact details of this disclosure, and the latter, therefore, is to be understood from an illustrative, rather than a restrictive standpoint.

The inventive idea involved is capable of receiving a variety of mechanical impressions, one of which for the purpose of illustration, is shown in the accompanying drawings, in which Figure 1 is a plan view partly in section showing the layout of my improved heating system and control;

Fig. 2 is a fragmental sectional View taken on line 2-2 Fig. 1;

Fig. 4 is a fragmental sectional view taken on line 4-4 Fig. 1;

Fig. 7 Yis a diagrammatic front View thereof;

Fig. 8 is a sectional view showing the switch mechanism operated bythe garage door;

Fig. 9 is a similar view of the control switch mechanism operated by a lock on the ofce or other door which is locked at night and normally unlocked during the day, and

Fig. l0 is a wiring diagram showing the electrical connections between the various controls and the fan motor.

Referring now to the drawings in detail, 2U indicates a boiler room in which there is located a hot water boiler 2| which is enclosed by a jacket or metal housing 22 into which there opens a fresh-air duct 23 and a recirculating-air duct 24. The fresh-air duct comprises an upper horizontal section 25 which extends through a wall 26 into the atmosphere and is covered by a rain hood or louvre 2l, and a vertical section 26 which merges with the recirculating duct at the entrance into the jacket 22. The recirculating duct opens into a heated room 29 and is provided with a grille 30.

To the upper portion of the jacket 22 there is connected a suction fan or blower 3| by means of a pipe connection 32. The blower or fan 3| is driven by a motor 33 and draws air from the outside as well as from the room 29, passes same around the boiler 2| and a hot water heater 34 where it is preheated before it enters the blower from whence it is expelled through hot-air ducts 35 extending from the blower casing 36 into automobile garage or repair shop 31.

The said garage or repair shop may be provided with one or more vertically sliding doors 4|] only one of which is shown in Fig. 1 of the drawings. Normally when the door 40 is closed, it engages a spring pressed plunger 4| of an electric switch 42 to close the electric circuit by contacting two terminals 43 and 44 having lead wires 45 and 46 respectively which form a part of the electric circuit shown in Fig. 10 for controlling the operation of the fan and motor. It will be seen that when the door 42 is closed, the electric circuit will be completed and the motor and fan will operate and when the door is slid open the contact will be broken and the motor and fan will stop to prevent same from blowing hot air into the garage which will be dissipated through the open door.

Hooked up with the hot water boiler 2| is a booster pump 41 driven by a motor 43 for aiding in the circulation of the water through the said boiler 2|, hot water heater 34, and the radiators 49, 50 and 5|. The booster pump motor 48 is in series circuit with the fan motor 33 so that the pump operates only when the fan is operating. Water is supplied to the boiler 2l through a pipe 52 and the water passes through the boiler and out through a pipe 53 to the special heater 34 and through a pipe line 54 which leads to the radiators lli), 59 and 5I. The hot water from the heater 3d is returned to the boiler through a pipe line 55 and 55a and the water from the radiators is returned through a pipe 56.

The system is shut down at night and through an electric switch operated bythe locking of a door t@ which may be the oince door or any other door. When the said door is locked the lock-bolt 6l (Fig. 9) operates an electric switch 62 to swing a spring-pressed lever 63 and break the electric Contact between the said lever and a Contact plate d. This action stops the motor and fan, and also de-energizes an electro-magnet 64b, the armature Gill@ of which is connected mechanically to a lever arm 65. operably connected to a lever @5 nxed to the pivot 6l of a damper 68 in the vvfresh-air duct section 25. When the said electromagnet 65h is cie-energized its armature is in the position shown in Fig. 6 with .thedamper 61 closed, and the nre damper 69 -opened and the ash-pit damper l vclosed to shut oi lthe draft of the boiler. Simultaneous adjustment of the dampers 5S, 59 and l@ is accomplished by means of chains or cords 'll and 12 which pass over sets of pulleys i3 and lli, the chain or cord 'Il having one end connected to one end of the lever 66, its other end connected to oneend of a lever or rocker bar 'l5 pivoted at 16, and the chain or rope l2 having an intermediate portion secured to the opposite end of the lever and its ends secured to the dampers 69 and 10.

-Referring to Fig. of the drawings 80 and el are the main electric supply wires which are connected to terminals 82 and 83 which may be closed by a switch 84 toclose the electric circuit. When the said switch 84 and the door 40 are closed and the oice door 6l) unlocked, the circuit will `.be closed and current will flow through to operate the fan motor, boostermotor and the various dampers. Suitably connected in the elecy tric circuit is a relay system 85 and a thermostat ing system which will prevent the dissipation oi heat through the open door of the room being heated, and also prevent the freezing of the water in the system when same is shut oi for the night. The prevention of the heat dissipation is due to the fact that heat supply is automatically stopped by the opening of the door, and the water is prevented from freezing due to the fact that as long as there is any fire in the boiler the water be suiiiciently warm to circulate through the system.

It will also be seen thatl I have provided positive means for automatically shutting oi the system at night by merely locking a predetermined lock.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:
